Because I Missed My Bestie Too Much, My First Love Collapsed

My best friend and I grew up together. We lived close to each other. We went to elementary school and middle school together, and were admitted to the same university. We both made good boyfriends in college. However, I didn't expect that my relationship was going smoothly, but my best friend's boyfriend abandoned her. In the end, my best friend left for another country to heal her emotional intelligence. I cared about her all the time, but it made my first love boyfriend jealous.
